Ironically the Unix philosophy doesn't even really apply to Unix itself - it mainly just applies to GNU tools. Unix is a general purpose operating system for computers of all shapes and sizes. You can't get much more generic than that.
It's still built on a simple kernel that doesn't do much and a user land of many independent processes. The philosophy doesn't forbid generality, it just encourages a "federalist" organization of cooperating programs communicating through simple kernel institutions (files, sockets).
